JOHN R. BRINK, OF GRAHAM, MISSOURI.

WIND-ENGINE.

SPECIFICATION forming part of Letters Patent No. 232,673, dated September 28, 1880. Application filed June 26, 1880. (No model.)

To all whom it may concern Be it known that I, JOHN ROBERT BRINK, of Graham, in the county of Nodaway and State of Missouri, have invented a new and valuable Improvement in Wind-Engines; and I do hereby declare that thewfollowing is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing, making a part of this specification and to the letters and figures of reference marked thereon.

The drawing is a representation of a perspective view of the wind-wheel.

Thisinvention has relation to improvements in wind-engines; and it consists in the construction and novel arrangement of parts, as hereinafter shown, described, and particularly pointed out in the claim.

In the annexed drawing, the letter Adesignates the wind-wheel, rotating horizontally around or on a vertical spindle at the top of a suitable tower, and having the radial parallel arms or spokes a a. arranged in pairs, the one above the other, and projecting from the horizontal spiders S S. These armscarry in their outer ends the vertical rods B, upon which rotate horizontally, between said arms, the wind-bladesO. These blades are designed to be made of a stift' nonflexible material, and are provided on their upper and lower edges with clamps E E, hating the projecting arms b I), having each one or more perforations, 6, arranged at intervals of equal length. These arms are parallel to each other, and are arranged usually at a distance from one end of the blade equal to one-third of its length.

The first set of perforations 'i is set off from the blade, as indicated, the second set somewhat farther, and the third farther still; consequently the wind-blades assume a position oblique to the course of the wind on the far side of the wheel, and on the near side they cut it. Thus they are designed to catch the Wind, and may be adjusted to run with less breeze by adjusting the fans or blades farther from the arms a. The fanblades are also and justable, sliding in the clamps E E, so as to lengthen or shorten thetailportion,whereby the speed of the Wheel is rendered less or greater. In other words, if the tails of the fans are lengthened the fans will follow the course of the ends of the arms a more nearly and the speed of the wheel will be lessened, whereas if the tails are shortened the fans will take a more oblique position and the speed of the wheel will be increased.

What I claim as new, and desire to secure by Letters Patent, is-- In a wind-wheel, the combination, with the horizontal spider or spiders S S, having the parallel arms a a and the vertical rodsB, of the horizontallyrotating adjustable blades 0, having the sliding clamps E E, and arms I) b, projecting therefrom,and provided with the perforations i, set off therefrom at equal intervals and adapted to receive the said rods, as shown and described.

In testimony that I claim the aboveI have hereunto subscribed my name in the presence of two witnesses.

JOHN ROBERT BRINK.
